BAG FASTENER.

`applicativa ined Amay 25,

Thisinvention relates to` devices for se- `curing `the frame sides ofbags in juxtaposition and` has as one ofits objects to provide meansforlatching the securingmeans `when in an adjustedjposition, thelatching means beingA `resiliently held and actuated by a hand knob.

Afurther feature is in the provision of a fknob of artistic appearancerotatably mounted `onta stem hinged to one ofthe frame members totiltthe stern vwhenreleasing a catch Ifixed on the mating frame member, inaddition toitslatching "feature whichis acceui- `plishedbypartialrotation of the knob.

These and other objects, which will become apparent fas the descriptionprogresses, are Vattained `by the novel construction `and combination ofparts hereinafter de-` scribedand shown iin the annexed drawing formingpart hereof, and in which Figure 1 isaperspective view of a conventionaltype of bag frame' showing anapplication of anembodiment `of theinvention. i i

Figure 2 is an enlarged transverse sec tional view of the frames 'andvcatch elements thereon. V y

`li`igure 3 is a partial longitudinal sectional `view of the saine. f

Figure 4 `is a plan viewof the lframe and catch element thereon with theornamental object removed.` lFigure is a perspective view oftheseveralelements in `detail "showing their rela tive position when assembled.

A common typeofvba g frame is illustrated in Figure l, the sameconsist'ingof two side elements 1() and r11 of :channel shaped crosssection, pivoted together by rivets 12 at the ends of their angularprojecting ends.

The rear side frame 11 has an elongated slot- 13 in the center of itsouter edge through which freely passes a flattened loop 14 formed on theenlarged circular hollow base 15 of a post 16 held normally erect aslater described, the post being cylindrical and terminating in arectangular projecting lug 17 provided with a slot 18 in its extremeend.

It is to be noted that the loop 14 extends downwardly from the base atone side thereof, so that the axis of the base is centered substantiallymidway of the frames, and is held tightly by the flattened portion 19 ofa torsion spring 20 passed through the 1927. Serial i No. 193,-965.

bight of the loop 14 and disposed in the in terior of the channel frame11, the op- Aknob body 22having hollowbase 23, en-

circling the post base 15, and terminating in a fiat plate flange 24;having flattened sides `25, resting directly on the upper surfaces ofthe bag frames.

Rlgidly fixed on the mating side frame is a stud 26 .having `an angularinner, rear faceadapted to enga-goth@ edge of the flange i 2dandbase 15,causingthe post and lrnobfto y tilt `rearwardly until the stud hasbecome fully entered within the chambered portion of the base, whereuponthe torsion spring 2O operates to move the post and knob forwardandretain the llug in the chamber, holding the frame sides tightlyclosed..

Also rigidly secured on the frame side 10, at uniform spaced distancesfrom the stud 26,'are ya pair-of opposed upstanding keeper -plateelements 27, 4having longitudinally n curved `or bevelled upper faces,the space `between these elements `being receptive of the knob `base 23while the ends of plate 24 may enter undercut recesses 28 in theadjatcent ends of the elements 27.

The enlarged'upperportion ofthe knob 22 is provided with a knurled band29 to facilitate 'turning by Vthe lingers and contains an annular recess30 having a iiooring level withithe `upper end of the main portion of`the post 16, as best seen in Figure 3.

A square block 31 having an opening 32 is iixed on the extending stein17 of the post and impinging against one of the four flat sides of theblock is the arm 33 of a spiral spring 34, the other end 35 of which isoutturned and entered in a groove in the wall of the knob chamber 30,thus preventing the spring from rotating in the chamber except as theknob is turned.

Disposed over theblock 31 and spring `34 is a flat disc 36 having anopening 37 through which the end of the stem 17 passes, the sternbeingupset thereover by spreading the notch 18 as at 38 in Figure 3.

The knob is completed by inserting an ornamental object, as the stone39, within a counterbored space 40 above the chamber 30 and spinning thethin wall 41 of the knob, above the band 29, inwardly to permanentlyretain the stone in place.

In operation, when it is desired to latch the bag against intrusion, theknob is turned to position the ends of the plate flange 24 within therecesses 28, as shown in Figure 1, at which time the action ofthe spring34 against the side of the block 31 retains the knob in adjustment andholds the vstud 26 within the chamber of' the post base Q3, preventingseparation of the sides.

When it is required that the bag be opened,

'f the knob is turned through an angle of ninety degrees, the springpermitting the corner of the block to pass by exerting force on theknob, and the ends of the plate flange 24 become positioned transverselyof' the frames to move upwardly between the ends ofi' the keeper plates27 when the knob and post are pressed rearwardly, thus liberating thestud and permitting the bag to open, the knob being retained inreleasing posi- `tion by the combined action of the spring and blockuntil further rotated.

Although the foregoing is descriptive of the preferred embodiment of theinvention, it will be apparent that minor changes may be made in itsconstruction, without the exercise of invention. i

Having thus described my invention, what claim as new'and desire tosecure by Letters Patent, is

1. A bag fastener comprising the combination with a pair of hingedframes, of a tiltable post mounted on one ofsaid frames, a torsionalspring in the frame to retain said post normally erect,` said posthaving a rhambered base,` a stud fixed in the other frame` said studbeing engageable in the.

chamber of said post, a knob revolubly mounted on said post, keepersfixed on the stud carried frame, andmeans on said knob engageable bysaid keepers when in oneposition and tree therefrom, when the knob is inanother position.

A bag fastener comprising the combina- 'tion with a pair of hingedframes, of ay post hinged on one of said frames, means to resilientlyretain said post erect, a. stud fixed on the mating frame, means in saidpost to engage said stud, a` knob rotatable on said post, means on saidpost to resiliently retain said knob in an adjusted position, opposedkeepers on the mating frame, and means on said knob to engage saidkeepers.

3. In a bag fastener having a pair of hinged frames, 'a post hinged onone of the frames, a `knob revolubly fixed on said post, ay torsionspring engaged with said post to retain it normally erect, a stud on theother frame adapted to engage said post, keepers on the last namedframe, said keepers having undercut-recesses, and a plate fixed on saidknob to become engaged or disengaged with respect to the recesses ofsaid keepers.

4. In a bag fastener having a air of hinged frames, a tiltable postreslliently mounted on one of Asaid frames, said post having a chamberedbase, a stud on the other frame engageable-in the ehambered base, a pairof undercut keepers on the last named frame, a. knob completelyenveloping said post, an elongated flange on the base of said knob, saidfiange being engageable with said keepers, a. rectangular block fixedonthe end of said post, and a spring fixed in said knob to impinge onthe edges of said block whereby the knob is resiliently retained inadjusted position.

5. In a bag fastener having a pair of hinged frames, a tiltable postresiliently mounted on one of said frames, a stud fixed on the matingframe to engage in the base of said post when upright, a pair of keepersadjacent said stud, a chambered knob completely enveloping said post, afiange on said knob to engage said keepers, a block fixed on said postwithin the chamber of said knob, a spring fixed in the knob to imp'nge,the edges of said block, a disc on said `post to retain saidsbloek,spring and knob thereon, and means integral `with said post for securingsaid dise in operative position. This specification signed and witnessedthis 12th day of May, 1927.
